TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALFRED IvER-S, of the city and State of New York, have invented, made, and applied touse a certain new and useful Improvement in Stationary Wash-Basins; and I do hereby declare the following tobe a. full, clear, and exact description o f the said invention, reference being had to the annexed drawing,v

making'part of this specification, wherein- Figure 1 is a vertical section of the said basin; and

Figure 2 is a sectional plan at line :u :r of fig. 1 at one side of the basin where the overflow pipe connects with said basin. A

Similar marks of reference denote the same parts.

Basins have heretofore been made in which a cluster of holes at one side has opened into an overow pipe, but in practice it is often found that these become partially stopped, and are inadequate for venting the water that may run into the basin when the faucet is left open through accident or carelessness. Effort-s have been made to remedy this 4diiiiculty by the introduction of a range of holes opening into awater-way around the basin. The object of my invention is to form a combined overiiow and trap that is suiiiciently large for allowing the water to vent itself and not overflow the basin, and at the same time the water in the basin closes the escape# orice so as to exclude smell. It is found that the pipe passing to the overflow frequently allows an unpleasant odor to enter the apartment in consequence of a defect in the bend or trap, or from the 'water being drawn out of it by the siphon action. My invention prevents this dificulty by causing the Awater in'the basin to close the I opening into said pipe, and preventing disagreeable odors passing outA of the same; and my improvement also allows for the opening from the basin to the overflow being cleaned much more easily thanthe` holes heretofore employed. Y l l Y My invention consists in a basin formed with a pendent {ia-nge on theline'of'tbeintcrior of the basin, and with a slot between its lower end and the basin itself, which'at this point is formed with an odset., producing a water-way between the said pendent flange and the exterior of the basin, which communicates with an overilow pipe at one side of the basin, the entrance to which is higher than the said slot, so that the water will rise in said basin and immerse the slot before it flows away by the overiiow.

In the drawing, a represents the basin, with the opening b at the bottom for receiving the usual waste pipe and plug. c is the ange around the upper end of the basin, by which it is sustained beneath a slab, as usual. d is the pendent ange formed with the basin, having its interior surface corresponding to the contour of the interior of the basin. e is the slot between'the lower edg'e of the ange d and the basin, said basin at this point being formed with an oiset, so that the vwater-way f is left between the flange and basin and'g is the overflow pipe attached at one side of the basin, and of a. capacity to vent the water that may at any time be allowed to continue running into the basin. z'is a dam or ledge at the entrance to the overflow pipe g, to cause the water in the basin to rise higher than the slot e before it runs away by said pipe g, so that the iiange d'acts to trap any offensive smell that `might otherwise pass out from the overflow pipe. s

What I claim, and desire to secure by Letters -Patent is- The pendent ange d and slot e, in combination with the dam t' and pipe g, substantially as and for the purposes specified.

In witness whereof I have .hereunto set my signature this twenty-second day of December, A. D 1866.

ALFRED IVERS.
